Abstract
A disposable heating unit for use for heating the contents of a container, includes a first region containing a combination of at least two solid substances which undergo an exothermic chemical reaction which is not spontaneous at room temperature. Adjacent to the first region is a second region containing at least a first reagent. A storage cell is configured for releasing the liquid containing a second reagent into the second region. The first and second reagents undergo a spontaneous exothermic chemical reaction when brought into contact, thereby initiating the exothermic chemical reaction of the solid substances.
Claims24
A disposable heating unit comprising a housing including:
- (a) a combination of at least two solid substances which undergo an exothermic chemical reaction which is kinetically not spontaneous at room temperature;
- (b) an initiation region containing at least a first reagent;
- and
- (c) a storage cell containing a liquid including at least a second reagent, said cell being configured for releasing said liquid into said initiation region, said first and second reagents being such that, when brought into contact at room temperature, they undergo a spontaneous exothermic chemical reaction, thereby initiating said exothermic chemical reaction of said solid substances.
A method for heating the contents of a container comprising:
- (a) providing a housing in thermal communication with the contents of the container, the housing containing a mixture of at least two solid substances which undergo a primary chemical reaction which is exothermic but is not kinetically spontaneous at room temperature;
- and
- (b) activating said primary chemical reaction by combining two reagents which undergo an exothermic chemical initiation reaction which is spontaneous at room temperature.
